Buy-Side OMS
Independent OMS implementation consulting for asset managers, hedge funds, and institutional investment firms. Platform-specialist expertise across Bloomberg AIM and Charles River IMS — without the vendor agenda.
The challenge
OMS vendors position implementation as a service they provide. The reality is that vendor professional services teams are optimized for go-live velocity, not operational quality. A system that technically goes live on schedule but requires six months of remediation before the trading desk trusts it is not a successful implementation. It is a delayed failure.
The buy-side OMS implementation problem is not a technology problem. The software works. The challenge is in the translation work between how your firm actually trades, allocates, and settles — and how the OMS is configured to support those workflows. That translation requires someone who understands both the platform and the business it runs. Vendor PS teams understand the platform. They do not understand your business. Generalist technology consultants understand neither well enough.
For COOs, CTOs, and platform sponsors at buy-side firms, the right question before selecting an OMS consultant is not "do they know the software?" Every credible consultant knows the software. The right question is: "Have they delivered this at a firm with a similar mandate, in similar market conditions, with similar counterparty relationships?" That specificity of experience is what separates implementations that work from implementations that require remediation.
Platform coverage
Implementation, compliance configuration, FIX connectivity, custodian integration, allocation workflow design, and platform optimization for firms running Bloomberg Asset and Investment Manager. Appropriate for equity managers, multi-asset firms, and hedge funds with Bloomberg terminal infrastructure already in place.
Full-lifecycle CRD delivery for institutional buy-side environments. Compliance rule mapping, IBOR configuration, T+1 settlement readiness, and data migration from legacy OMS platforms. Appropriate for large asset managers, pension funds, insurance companies, and firms with complex compliance requirements.
Not sure which platform is right for your firm? The Bloomberg AIM vs. Charles River platform comparison and the OMS Readiness Assessment can help clarify the right direction before you commit to either platform.
Who this is for
PBW Professional Services works exclusively on the buy side. The OMS configuration requirements for a registered investment adviser managing long-only equity mandates are different from those of a prime brokerage technology team. The compliance rule logic for a pension fund is different from the execution infrastructure for a market maker.
This focus is not a limitation — it is a specialization. We understand the compliance environment, the counterparty relationships, the custodian economics, and the operational workflows that define how buy-side firms actually operate. That understanding shapes every implementation decision we make.
Engagements are typically led directly by Philip Williams, a senior OMS practitioner with institutional buy-side experience across both Bloomberg AIM and Charles River IMS. The consultant who scopes the engagement delivers it. There is no junior team waiting in the background, and the scope is not renegotiated after signatures.
Engagement types
Full-lifecycle deployment for firms standing up their first institutional OMS or replacing a legacy system. Requirements through go-live. Typical timeline: 12–18 weeks. Includes compliance configuration, integration to custodians and brokers, UAT management, and production cutover.
Structured migration from a legacy OMS — or from spreadsheet-based operations — to Bloomberg AIM or Charles River IMS. Data migration, parallel run management, and cutover planning. Includes change management support for trading and operations teams.
For firms already live on AIM or CRD but underutilizing the platform. Workflow audit, compliance rule review, integration diagnostic. Typically a 4–6 week engagement that addresses the manual touchpoints and configuration gaps that accumulated during the original implementation.
Ongoing senior OMS advisory for firms that need practitioner expertise without a full-time hire. 20, 40, or 60 hours per month on retainer. Appropriate for firms going through regulatory changes, system updates, or operational changes that require OMS expertise episodically.
Use the OMS Readiness Assessment to benchmark where your firm stands, or schedule a scoping call to discuss your specific implementation requirements.
